Every data science project starts with data and this chapter begins in the same manner. For this recipe, we will dive into a dataset that contains fuel efficiency performance metrics, measured in Miles Per Gallon (MPG) over time, for most makes and models of automobiles available in the US since 1984. This data is courtesy of the U.S. Department of Energy and the US Environmental Protection Agency. In addition to fuel efficiency data, the dataset also contains several features and attributes of the automobiles listed, thereby providing the opportunity to summarize and group data to determine which groups tend to have better fuel efficiency historically and how this has changed over the years. The latest version of the dataset is available at http://www.fueleconomy.gov/feg/epadata/vehicles.csv.zip, and information about the variables in the dataset can be found at http://www.fueleconomy.gov/feg/ws/index.shtml#vehicle. The data was last updated on...

Overview of this book
As increasing amounts of data are generated each year, the need to analyze and create value out of it is more important than ever. Companies that know what to do with their data and how to do it well will have a competitive advantage over companies that don’t. Because of this, there will be an increasing demand for people that possess both the analytical and technical abilities to extract valuable insights from data and create valuable solutions that put those insights to use.
Starting with the basics, this book covers how to set up your numerical programming environment, introduces you to the data science pipeline, and guides you through several data projects in a step-by-step format. By sequentially working through the steps in each chapter, you will quickly familiarize yourself with the process and learn how to apply it to a variety of situations with examples using the two most popular programming languages for data analysis—R and Python.
